To all whom t may concern:

Be it known that I, JOHN M. ABRAMS, a citizen of the United States, residing at Bentley Manor, in the county of Richmond and State of. New York, have invented certain new and useful lmprovements in Tires, of which the following is a specilication.

My invention relates to tires of that class known as 'cushion tires.

It has 'for its' object to provide a tire which will possesathe advantages of a pneumatic tire in that 'iti is elastic and resilient, but which will avoid the disadvantages of the pneumatic tire in that its elasticity or resiliency are in no wise affected by puncture.

It has for a further object to provide a tire which is more durable, simpler in construction and more easily applied and removed than a pneumatic tire or other cushion tires now in use.

It has for a further object to provide a tire having a spiral metal spring therein to augment the elasticity and resiliency of the outer casing.

lt has for a further object to provide a tire of the character described, having a leather tube between the outer casing and spring to prevent injury to the outer casing by contact of t-he spring therewith and provided with a spiral groove which receives the spring and holds it in place and spaces its convolutions.

lt has t'or a further object to provide a a tire of the character described, having the outer casing split longitudinally, the leather tube split longitudinally and a longitudinal supporting strip located between the outer casing and tube and extending across the space between the longitudinal edges of the casing and tube and is provided with a longitudinal rib extending into the space between the longitudinal edges of the casing.

In the drawings: Figure 1, is a fragmen tary sectional View showing my tire applied to a wheel.` Fig. 2, a transverse sectional view showing my tire`applied yto a wheel.

. Fig. 3, a transverse sectional View of the easing. Fig. 4, a perspective view of a portion of the supporting strip. Fig. 5, a fragmentary sectionall view of the tube. Fig. 6, a transverse sectional view of the tube. Fig.

,7, a transverse sectional view of the tube and spring therein.;V Y. I

Referring to the drawings illustrating my invention, in which like reference characters designate corresponding parts, 1` designates the rim of a wheel, 2 the spokes and 3 the shoe of a tire, consisting of an outer casing split longitudinally to form two longitudinal.

edges and provided with lateral

longitudinal flanges

4 and 5. The tire is secured to the rim, on oneside, by means of a ring 6 which engages the flange 4 of the outer casing and the Hangs 7 of th.n rim and secured on the' other side by means of a ring 8 which engages the flange 5 of the outer casing and a ring '9 which engages the ring'8 and the flange 10 of the rim. The outer casing 34 is provided with recesses 11 in its interior: along its longitudinal edges for the purpose to be hereinafter mentioned.

A leather tube 12 is located in thelouter casing and is provided with a spiral groove 13 1n its mner circumference in which seated a metal spiral. spring 14. 'Ihisftube- 12, on account of separating the metal spring 14 from the rubber outer casing 3, prevents.'

wear and other injuries tothe outer casing:

which would result from the metalspring` contacting therewith, on account of being made of leather forms a tough flexible surface for the metal spring to bear againstand on account of being split lo ltudinally is easily'placed on or remove from the spring. The A groove 13 in the tube 12 retains the spring 14 therein and Spaces itseonvolutionsso that,when pressureisplaced on thespring, its convolutionswill not be forced together or apart and lessen its spring action.

A longitudinal supporting strip 15, preferably of leather, is located between the tube 12 and the outer casing and extends across the space between the longitudinal edges of the casing and tube into the recesses 1l Aand is provided with a longitudinal rib 16 which extends into the space between the longitudinal edges of the casing and bears on the rim 1 of the wheel. The strip 15 is made ofsuch length that when its rib 16 is in vthe center.

of the space between the longitudinal edges of the casing 3, its ends will extend short of the ends of the y slots 11 thus, when it is i desired to remove the tire from or secure it on the rim 1, the strip 15 and casing 3 can be forced laterally in the proper direction to allow the ring 9 to be removed or inserted as required. This strip 15 on account myself to the details of constructioi'i and ary rangement as herein described and illus-A trated, as itis manifest that variations and modifications may be made in the features of i construct] on and arrangement 1n the adaptation of the device to various conditions of usewithout departing from the 'spirit and scope,of my invention and lmprovements.

therefore reserve the right to all such varia-v tions and modifications as properly fall within the scope of my invention' and the terms of the following claims. "i I claim: y

1. In a tire, an. outer casing split longitudinally, a leather tube in said easing having a spiral groove and a spiral spring seated in said groover and its eonvolutions being spaced thereby, substantially as described.

2. ln a tire, an outer* casing split longitudi'nally, a leather tubein said casing split longitudinally and having a spiral groove and a-spiral spring seated in said groove and its convolutions being spaced thereby, substantially as described.

3. ln a tire, an outer casing 'split longitudinally and having recesses along its longitudinal edges, a tube in said casing split longitudinally, a spring in said tube, means retaining said spring in said tube and spacing its convolutions and a longitudinal supporting strip located between said casing and tube and extending across the space between thc longitudinal edges of said easing and tube into the recesses in said casing, substantially as described.

4. In a. tire, an outer easing split longitudinally, a tube in said easing split longitudinally7 a spring in said tube, means retaining said spring in said tube and spacing its convolutions and a longitudinal supporting strip located between said easing and tube and extending across the space between the longitudinal edges of said casing and provided with a longitudinal rib extending into the vspace between the longitudinal edges of said easing and adapted to contact with the rim of a Wheel, substantially as described.

In testimony whereof, I have signed my name in the presence of two subscribing witnesses.

JOHN M. ABRAMS.
